Facile Way of Synthesis for Molybdenum Iodides.

Molybdenum iodides are prepared based on a new way of synthesis, namely, via reductive metathesis reaction of MoCl5 with SiI4. MoI3 was formed at 150 °C. Mo6I12 and the new molybdenum iodides Mo6I16 and Mo6I18 with the well-known [Mo6I8]4+ cluster core were obtained in the temperature range 550-600 °C. Compounds were structurally characterized by powder and single-crystal X-ray diffraction techniques.
